Write MIPS code to implement a leaf procedure for the following C function: int leaf procedure (int x, int y) {int i, a; a = x + y; a = a + i; return a Assume that the variables x and y are passed from argument registers $a0 and $a1 respectively. The returned value should be stored in register $v0. Note that you need to use stack to store any other registers if you use them in this procedure
